Hey Printer Rick, Sorry, at this point in time it is impossible to rotate, with the transform effect, without getting that unwanted curve. Don't know what you have against expanding your work, but that is how you solve this problem. The easiest solution is to expand your image, select all the square, and center align them.

That way you can adjust it later if you like.
